I was hoping to extend the range of my sony wireless headphones. I like to listen to something while performing the mindless drudgery of mowing my lawn, only the signal doesn't extend to the end of my lot. the package said it had a range of 70 feet but that is something of an exaggeration. I'm lucky if it goes more than 50 feet.If they don't sell repeaters for Wireless headphones, somebody should invent one. .
